[0002] Flexible Printed Circuit (FPC) is a highly reliable and flexible printed circuit board made of polyimide or polyester film. With the innovation of electronic products, FPC products have thinner and more sophisticated circuits. More and more products need to be produced using a single horizontal line (such as Figure 1 When these production processes are used, new challenges are posed to the equipment's transmission capabilities.

[0003] When producing a single horizontal line, a guide fixture is required to pull it through the horizontal line. Otherwise, problems such as jamming, curling, and corner bending will occur, which will cause the product to be scrapped, affect the quality of other products, cause equipment damage, and increase maintenance costs. It will also cause the equipment to be contaminated, requiring increased maintenance, affecting production capacity and efficiency.

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the utility model, many technical details are proposed in order to enable readers to better understand the utility model. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection of the utility model can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the utility model. The various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0041] The utility model provides a guiding structure of a flexible circuit board, please refer to Figures 1 to 3The guiding structure 100 of the flexible circuit board includes a clamp structure 1 and a base structure 2, wherein the clamp structure 1 has a clamp body 11, a support portion 12 extending longitudinally from the clamp body 11, and a plurality of clamping portions 13 extending longitudinally from the clamp body 11, wherein the length of the support portion 12 extending longitudinally exceeds the plurality of clamping portions 13, and the plurality of clamping portions 13 are arranged at intervals in the transverse direction; the base structure 2 has a base body 21, and a pressing groove 22 provided on the base body 21; wherein when the support portion 12 is inserted into the pressing groove 22, at least the plurality of clamping portions 13 are exposed from the pressing groove 22; when the support portion 12 is inserted into the pressing groove 22 and presses down the clamp body 11, a clamping space 3 for inserting the flexible circuit board 200 is formed between the plurality of clamping portions 13 and the support portion 12.

[0042] It should be noted that when the support portion 12 is inserted into the pressing groove 22, at least the multiple clamping portions 13 are exposed from the pressing groove 22, that is, when the support portion 12 is inserted into the pressing groove 22, the clamping portion 13 will not extend into the pressing groove 22, so that when the support portion 12 is bent, the clamping portion 13 is tilted to form a clamping space 3.

[0043] In the prior art, single-sheet horizontal line production is usually completed with the assistance of tape. By using tape to connect the guide fixture to the flexible circuit board, there are the following problems: more manpower is required to paste the guide board (for example, 2 people / line), the tape is not firmly posted, and there is a risk of falling off, floating, and board jams. It may even cause the adhesive component of the tape to remain on the surface of the flexible circuit board, contaminating other flexible circuit boards and the production line. Dry film will remain where the tape is pasted, forming foreign matter and defective products in the later process. In addition, manual tape pasting is easy to stick to the mark point inside the flexible circuit board, causing the later process to be unable to locate and cause scrap.

[0044] See also Figure 2 During operation, insert the support portion 12 into the pressing groove 22; press the chuck body 11 downward, the support portion 12 will bend, and the clamping portion 13 will tilt upward, so that a clamping space 3 for inserting the flexible circuit board 200 is formed between the multiple clamping portions 13 and the support portion 12; then insert the flexible circuit board 200 into the clamping space 3; after the flexible circuit board 200 is inserted into the clamping space 3, pull the support portion 12 out of the pressing groove 22, please refer to Figure 3 and Figure 4 At this time, the flexible circuit board 200 is clamped between the support portion 12 and the clamping portion 13, which solves a series of problems caused by the need to use tape to connect the flexible circuit board in the prior art.

[0045] More specifically, after the flexible circuit board 200 is inserted into the clamping space 3, the support portion 12 is pulled out of the pressing groove 22, and the flexible circuit board 200 is clamped between the support portion 12 and the clamping portion 13. At this time, the clamp structure 1 guides the flexible circuit board 200 into the horizontal line body. After the production process is completed, the clamp is separated from the flexible circuit board 200. In this way, the production of a single horizontal line can be completed without using tape or the like.

[0046] See also Figure 5 and Figure 6 The support portion 12 includes a plurality of support members 121 extending in the longitudinal direction and a transverse arm 122 extending in the transverse direction. One end of the support member 121 is connected to the chuck body 11, and the other end is connected to the transverse arm 122. The plurality of support members 121 are arranged at intervals between the plurality of clamping portions 13. A support member 121 is provided between each two adjacent clamping portions 13, and the connection between the support member 121 and the transverse arm 122 is arranged beyond the plurality of clamping portions 13 in the longitudinal direction. By providing a plurality of support members 121 arranged between the plurality of clamping portions 13, it is convenient to support the clamping structure 1 when the chuck body 11 is pressed down to avoid bending and damage during pressing down. At the same time, the plurality of support members 121 can be bent by pressing down the chuck body 11, and the clamping portion 13 is tilted upward, and a clamping space 3 for inserting the flexible circuit board 200 is formed between the plurality of clamping portions 13 and the support member 121.

[0047] In this embodiment, the middle part of the support member 121 is hollowed out to reduce stress, so that the support member 121 can be bent smoothly when the clamp body 11 is pressed down. More specifically, each support member 121 includes two support arms 1211, one end of each support arm 1211 is connected to the clamp body 11, and the other end is connected to the transverse arm 122; the two support arms 1211 are arranged in a transverse interval and the two support arms 1211 are respectively arranged near one of the clamping parts 13. Please refer to Figure 6 For example, two adjacent clamping portions 13 include a first clamping portion 13a and a second clamping portion 13b, and two support arms 1211 include a first support arm 1211a and a second support arm 1211b. The first clamping portion 13a, the first support arm 1211a, the second support arm 1211b, and the second clamping portion 13b are arranged in sequence along the horizontal direction. At this time, the first support arm 1211a is arranged close to the first clamping portion 13a, and the second support arm 1211b is arranged close to the second clamping portion 13b. In this way, the size of the hollow space formed between the first support arm 1211a and the second support arm 1211b can be increased, thereby further reducing stress.

[0048] In addition, there is a gap between the transverse arm 122 and the clamping portion 13 along the longitudinal direction, so that the support portion 12 can be bent when the clamp body 11 is pressed down, and the clamping portion 13 can be tilted upward, so that a clamping space 3 for inserting the flexible circuit board 200 is formed between the multiple clamping portions 13 and the support portion 12. In this embodiment, the longitudinal spacing between the transverse arm 122 and the clamping portion 13 is H, 2.1mm≤H≤2.3mm. In other embodiments, H can also be 2.2mm.

[0049] In addition, the middle part of the clamping part 13 is hollowed out, so that the stress of the flexible circuit board 200 clamped between the clamping part 13 and the supporting part 12 can be reduced, and it is convenient to directly separate the clamping structure 1 from the flexible circuit board 200 after completing the horizontal line body process, and the flexible circuit board 200 is not damaged. More specifically, each of the clamping parts 13 includes a first pressing arm 131, a second pressing arm 132, and a third pressing arm 133, the first pressing arm 131 and the third pressing arm 133 are extended in the longitudinal direction, and the second pressing arm 132 is extended in the transverse direction; one end of the first pressing arm 131 is connected to the clamping body 11, the other end of the first pressing arm 131 is connected to one end of the second pressing arm 132, the other end of the second pressing arm 132 is connected to one end of the third pressing arm 133, and the other end of the third pressing arm 133 is connected to the clamping body 11.

[0050] See also Figure 7 and Figure 8 In order to facilitate pressing down the chuck body 11, the pressing groove 22 is inclined, and the inclination angle of the pressing groove 22 is A, 54°≤A≤60°, so that after the support portion 12 is inserted into the pressing groove 22; it is more convenient to press down the chuck body 11, and it is more convenient to insert the flexible circuit board 200 when the clamping space 3 is formed. In other embodiments, A can also be 56°, 57°, or 58°.

[0051] In addition, in order to ensure that the support part 12 is smoothly inserted into the pressing groove 22 and is easy to press down, and to ensure that the support part 12 does not slip out of the pressing groove 22 while pressing down, when the support part 12 is inserted into the pressing groove 22, the gap between the support part 12 and the groove wall of the pressing groove 22 is G, 0.25mm≤G≤0.5mm, so that the support part 12 can be smoothly inserted into the pressing groove 22 and is easy to press down. In other embodiments, G can also be 0.3mm or 0.4mm.
